increased consumption of oxygen and nutrients by muscle cells requires more blood supply. The functions of blood include delivering oxygen‚ removing CO2‚ removing heat and delivering nutrients and water. Therefore‚ blood flow is important in cellular respiration‚ which is the process where ATP is produced through the conversion of metabolites‚ also involving the consumption of oxygen and release of CO2 as a waste product. ATP is vital to skeletal muscle contraction‚ since the power stroke is facilitated

strength is influenced by the reduction of oestrogen. Some people are more at risk than others of getting this disease because it can be influenced by genetic inheritance. The environment can make a difference this is because exercise strengthens muscles and bones and can prevent osteoporosis. Cardiovascular system The heart pumps blood around the body. With age many individuals may develop narrowing of the arteries and other blood vessels due to fats such as chloestrol being laid down in the walls

List the four tissue types found in the human body. Describe an example of each type with their function and location. The four main tissues in the human body are connective‚ epithelium‚ muscle and nervous tissue. Connective tissue is an abundant nonliving extracellular matrix‚ located throughout the human body; such as the head‚ tendons‚ bone‚ and many more. It is the most widespread tissue in the human body and is the most durable tissue type. There are so many functions for this tissue‚ that

Another one is the Skeletal System (bones). It is made of about 206 bones‚ that are divided in tho categories: axial bones (in the body by itself) and apendicular bones (arms & legs). We have Joints too. Thei`re divided in Ball Socket (like elbow and shoulders) and sattle (fingers). This system`s function are movement‚ storage of minerals‚ blood formation‚ support of the body and protection of body parts. The next one is the Muscular System. It is composed of muscles (dah). The muscles are divided in

Epithelial tissue always rests on a basement membrane. The characteristics are: lack of visible interstitial space‚ many cells‚ and no blood vessels. A. Simple Squamous: (kidney slide). Look in the outer edge or cortex of the kidney to find a Bowman’s capsule. The lining of the Bowman’s

11. Identify the four basic types of tissues and the functions of each tissue type. There are four different types of tissue. They are; nerve‚ epithelial‚ connective‚ and muscle. The nerve tissue is made up of neurons that receive and transmit electrical impulses‚ this is their function. There are several different types of epithelial tissue. First there is simple squamous epithelium tissue. This is a single layer of cells that is in the lining of blood vessels‚ the lining of the pulmonary alveoli

The Usage of Anabolic Steroids 1. In case of muscles‚ hypertrophy is a process that is characterized by increasing of muscle cross-sectional area and mass. Changes primarily happen because of cells growth‚ rather than an increase in their number. There are several mechanisms that cause the hypertrophy of skeletal muscles. “The first measurable effect is an increase in the neural drive stimulating muscle contraction” (“Hypertrophy”). The process also includes the genetic response and protein synthesis
