Circulatory Framework

I am the Bob the heart. I am located just behind and slightly left of the breastbone. The system that works with me is the circulatory system. The circulatory system is an organ system that permits blood to circulate and transports nutrients, oxygen, carbon dioxide, hormones and blood cells. The circulatory system also helps forming cells in the body to nourish it and help fight diseases.

1.The fluid surrounding tissue cells is called? interstitial fluid.2.What are the functions performed by the circulatory system?-The circulatory system supplies oxygen and nutrients to our body by working with the respiratory system.- It also helps carry waste and carbon dioxide out of the body3.What is the fluid type that holds many of the human body fluids? Intracellular fluid4. Name fluids that are nearly identical in content except for proteins. Plasma and interstitial fluids.5.What function of blood is most critical to life on a second to second basis? Blood Regulation6.What fluid has the highest concentration of proteins? Intracellular fluids7.What is the most prevalent positive ion in interstitial fluids? Sodium8.What is the principal

The system works because in blood there are antigens and agglutinogens. In type A, only type A antigens on the red blood cells. Similar to this type B only has type B antigens. Type AB has both A and B antigens, which is why it is the universal recipient. Type O has neither A or B antigens making it the universal donor.

Unit D: Human Systems in Biology 20 is one of the main sections that becomes relatable to the Program of Studies (POS) for the Heart Rate and Exercise LabQuest activity. General Outcome #2 focuses on how students will explain the role of the circulatory systems and defense systems in maintaining an internal equilibrium. This further goes into measuring the students level of understanding the concepts of heart rate and the factors that affect it (Alberta Education, p. 41). Heart rate can then branch out into concepts of maximum heart rate, resting heart rate and recovery time. Through the LabQuest experiment, the main affecting factor was exercise and how that relates back to the fitness level of an individual [20-D2.3s]. Other key concepts found in the lab’s analysis questions then dealt with disorders of the heart [20–D2. 2sts]. Students are additionally "conducting investigations into relationships between and among observable variables" through the use of tools to gather information in regards to their heart rates [20–D2.2s]. Through group work activities, they are achieving collaborative work in measuring heart rate and other factors relating to the circulatory system [20-D2.4s]. To analyze and interpret, the POS explicitly states that students have the option in determining, from available data, the relationship between blood pressure and exercise [20–D2.3s a]. For the simulation, predominantly at the high school level, the

The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.

In this experiment, the purpose was to identify the effect of sedatives and stimulants on the circulatory system on the ghost shrimp and the black worm. We used caffeine as our stimulant and ethanol as our sedative. The shrimp was placed on a wet petri dish, where it was covered. After letting the shrimp rest for a few minutes, we placed it under the lowest light of a dissecting microscope. Then we located the heart, counted the number of beats in 10 seconds and multiplied it by 6 to acquire the beats-per-minute. In the next trial we dropped 0.5 mL of .0005 M caffeinated solution on the shrimp and waited 2 minutes before we measured the bpm. After the bpm was recorded, the shrimp was washed with spring water. The same procedure was performed

We have many important systems that help our body function. Two of the important systems are the cardiovascular system and the circulatory/blood system. Both the cardiovascular and circulatory/blood system have to deal with the heart. Without these two systems, we wouldn’t be alive. These systems can develop problems as we get older, so we have to make sure we take care of ourselves.

Every system is connected to each other, in different many ways. In our project microbe an us blood is the number one survival in the circulatory system,. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems.In our heart we have a pulmonary circulation is a short loop that goes from the heart to the loops and goes back again. The muscular system connects to the circulatory system. The muscular system is an organ muscular system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. The respiratory system is connected to the circulatory system,

In humans, hypertensive cardiovascular complications result mainly from alterations in small and large arteries. Vascular alterations are commonly attributed to factors associated with hypertension, such as aging or atherosclerosis. One in three adult in the United State has high BP. An additional 28% are at high risk for developing hypertension (Townsend, Wilkinson, Schiffrin, Avoilo, Chirinos & Weber, 2015).

The Bluefin tuna has a single, open circulatory system ("BBC - GCSE Bitesize Science - Circulatory systems and the cardiac cycle : Revision, Page 2", 2014). They have a simple two chambered heart as they are an organism which uses gills to oxygenate deoxygenated blood ("Two-Chambered Heart: Definition & Anatomy - Video & Lesson Transcript | Study.com", 2017). The heart structure consists of only one atrium and one ventricle. Blood travels from the ventricle through to the conus arteries (aorta in mammals) to the gills. Once the deoxygenated blood reaches the gills, it is oxygenated and gasses like carbon dioxide are extracted from it. After, the blood makes its way to the other organs of its body, replenishing them with nutrients and removing

veins to the tissues of the body. These walls do not let out blood but

Redox signalling is an electron transfer process that is crucial in biological systems. Redox signalling is found in many physiological and pathological systems within the circulatory system. Redox signalling is usually induced by an overproduction of reactive oxygen species (ROS) which can alter the functions of cell processes. Harris,(2012). ROS are radicals that contain one or more unpaired electrons and can be the oxygen radical superoxide or the non-radical hydrogen peroxide (H2O2). ROS can also contribute to vascular modelling by phenotype modification of the smooth muscle cells, growth and even the death of cells. This shows the need for redox signalling and it has many roles within the body. Harris. (2012). Redox signalling is important as exposure to oxidative stress can cause imbalances that can contribute to infections and toxins. Thiol based redox couples can form independent signals that can regulate any imbalances and are linked to any changes that occur in redox potentials. Harris. (2012). Cysteine is an amino acid and it can undergo oxidative modifications to perform different functions. Cysteine can form cross links to stabilise proteins and it functions as a reversible on/off switch in redox signalling. Paget,(2003). Cysteine is a nucleophile that can react under different conditions, due to the thiol functional group. Conte,et al. (2000). Thiols contain sulphur and hydrogen and this gives them a higher acidity than alcohols. . Redox cysteine thiols

there is no pumping mechanism to do so); veins have to be able to hold

Physics is known to be a natural science. It majorly entails the study of matter and the motion of matter through time and space, along with related concepts such as force and energy. Does the circulatory system apply concepts in physics as the blood circulates through the entire system? The circulatory system’s main objective is to transport blood throughout all the necessary parts of the body. The blood in effect transports nutrients and oxygen to these body parts and wastes away from these body parts to the organs that excrete them out of the body. The heart is the nerve centre of the circulatory system. This is so as it is this organ that pumps the blood that carries both the nutrients and wastes to the appropriate parts of the body.
