Digestive, Cardiovascular and respiratory systems.

Digestive systems.
The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the whole body. To achieve the goal of providing energy and nutrients to the body, six processes take place in the digestive system. ingestion secretion mixing and movement digestion absorption excretion There are 3 types of digestion:
Normal digestion - Breakdown of Carbohydrates, Proteins and Lipids to small solid substances that can be absorbed in the blood.
Mechanical digestion - physically breaking food down into smaller pieces.(teeth)
Chemical digestion - Breaking down food into simple substances using enzymes.
Cardiovascular systems.
The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.
Circulatory Loops
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

The respiratory and cardiovascular systems work together to perform the gas exchange function. Without gas exchange function, the cells would die, hence, it is needed for these systems to work together. Through respiratory system, the oxygen enters the body and then it is transported as oxyhaemoglobin to the cells with the help of cardiovascular system. The cardiovascular system also performs the work to transport the waste product carbon dioxide to respiratory system, that evacuates it. Hence, without respiratory system, the oxygen could not enter the body and it could not discharge the carbon dioxide waste. Without cardiovascular system, the oxygen and carbon dioxide could not travel the
Transport- Transportation of oxygen, nutrients and hormones to cells and removal of metabolic wastes such as carbon dioxide, heat and nitrogenous wastes.
The digestive system is made up of all different organs which starts at the mouth and finishes at the anus but on the way involves all other organs; these organs help to break down and absorb the food.
The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.
The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The
The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the
The respiratory system carries out gas exchange; it provides oxygen and disposes of carbon dioxide from the blood. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs where the carbon dioxide is removed and oxygen is put in. The blood then travels back to the heart where it is pumped throughout the body through arteries. Carbon dioxide in the form of carbonic acid and bicarbonate contribute to blood buffering so the pH level of the blood resists changes. The circulatory system delivers oxygen provided by the respiratory system throughout the body via arteries, such as the aorta.
Meanwhile, the left receives the now oxygen rich blood that comes from the lungs and is then pumped through the arteries. However, this time the left ventricle receives the
The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.
The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.
The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,
The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
The structure of the digestive system consists of organs that help break down food, absorb nutrients, and eliminate wastes. Organs that contribute to the breakdown of food include the mouth, esophagus, and stomach as well as the pancreas and gallbladder. Nutrients are absorbed through the small intestine, and remaining waste is eliminated through the large intestine and
As blood travels through the circulatory system, it is first pumped from the right side of the heart to the lungs through the pulmonary arteries and then separates into arterioles which split into capillaries. Here, the deoxygenated
The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the
