Investigation of Tissues Essay

Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides

Starvation results in a series of devastating events that can ultimately lead to death. When a person eats, the body extracts needed nutrients for cellular maintenance and repair. This requires energy which is provided for by the metabolism of the food. If we consume more than what is required at that time, our body stores the excess as adipose tissue or fat. This fat serves as a reserve of potential energy in times of a

3. Explain your prediction for the effect Na+ Cl- might have on glucose transport. In other words, explain why you picked the choice that you did. How well did the results compare with your prediction?

1. Name the circulatory system that carries blood from the heart to the lungs and back to the heart.

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

3. Describe the primary functions of each type of body tissue and give examples of each.

It doesn’t contain blood vessel and is nourished by the diffusion from the bone. Adipose, is another term for fatty tissue. It is common for under the skin and around the organs such as the heart, kidney and part of the digestive tract.

2-1: What are the characteristics of epithelial tissue? _Polarity, Specialized contacts, Supported of connective tissue, Avascular but innervated, Regeneration___

They are very strong, yet lightweight. Dense connective tissue, are cells crowded between collagen fibers. Loose connective tissue is the most common type of tissue in vertebrates. It holds the organs in place, and attaches to epithelial tissue. Reticular connective tissue is found around the liver, the kidney, the spleen, the lymph nodes, and in bone marrow. It forms a soft skeleton that supports. Blood is used to transport oxygen and nutrients to the cells.

The dermis contains elastic and fibrous tissues such as fibrillin, collagen and elastin. These tissues gives

On a molecular level, fat tissue is normally the largest organ in humans and is involved in mechanisms and pathways that deal with longevity. Fat tissue is not only involved in energy storage but is also important in immune and endocrine function, thermoregulation, mechanical protection, and tissue regeneration (Tchkonia et al., 2010). Adipose tissue is able to protect against infection and trauma. It is also able to produce and activate hormones, including IL-6, IGF-1, and glucocorticoids, as well as prevent heat loss (Tchkonia et al., 2010). Throughout life, changes in fat distribution and function is constantly occurring and in older individuals, these changes correspond to a number of health disorders like hypertension, cancers, cognitive dysfunction, and diseases like diabetes, heart attacks, and strokes, as previously noted (Tchkonia et al., 2010). As people age, their body composition increases in fat mass and decreases in muscle mass, regardless of their body weight or BMI (Dorner and Rieder, 2011).

Scientifically, obesity is construed as surplus adipose tissue. Adipose tissue emits multiple commodities, such as lipids and

In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue.

Under the residue of residues, the following interesting concept is outlined: “Grief is deemed appropriate in our society at a funeral, but not at a party. In other cultures, however, such judgments of propriety may be reversed. With regard to thought disorder, cultural anthropologists have long been at pains to point out that ways of thought are fundamentally different in different societies. What constitutes a meaningful human relationship, anthropologists also report, is basically different in other times and places. Likewise, behaviour that is bizarre in one culture is deemed tolerable or even necessary in another’’ (Scheff, 1970; 16)
