Answer:
Explanation:
The respiratory system which includes the organs used for breathing and the skeletal system which is responsible for body support and aids it proper movement interact and can be interwoven functionally in the following ways:
1. The bones in the nose called nasal conchae form swirl like shapes in the nose region that aids the passage of warm air from the nose to the lungs.
2. The centre of the human bones consist of the bone marrow which is responsible for the production and formation of red blood cells, white blood cells and platelets. These red blood cells carry oxygen from the lungs to other parts of the body like a transport system.
3. The thoracic or rib cage protects the lungs from damage and ensures stability.
Twisting or pulling a muscle or tendon can result in a strain. It can also be caused by a single instance of improper lifting or by over stressing the back muscles. A chronic strain usually results from overuse involving prolonged, repetitive movement of the muscles and tendons. In addition, there are several factors that put a person at greater risk for a back strain or sprain, including excessively curving the lower back, being overweight, having weak back or abdominal muscles, and tight hamstrings (muscles in the back of the thighs). Playing sports that involve pushing and pulling—such as weightlifting and football—also increases the risk of a low-back injury. Chronic strains happen slowly over time from prolonged, repetitive overuse of muscles. Chronic strains develop from using the same muscle groups in the same pattern, causing even small stresses to build on one another. Causes of chronic strain include:
Improper body mechanics or using the wrong muscle groups for a task, such as repeatedly lifting heavy objects using your back instead of your legs
Improper sports mechanics or techniques, such as habitually gripping a tennis racket too tightly or an incorrect golf swing
Participation in the same exercises in the same way, day after day
Poor posture
Use of the wrong equipment, such as running shoes without the proper support for your foot type
Ileum portion has Peyer's patches but jejunum portion is not having it
Explanation:
Small intestine can be divided into three parts they are ileum , jejunum and duodenum. Small intestine is a long , folded as well as narrow tube that extend from the stomach to the large intestine. Small intestine is that region where digestion takes place, small intestine mainly absorb nutrients from the food. Ileum and jejunum have Brunner's gland but duodenum do not have Brunner's gland. Ileum is having Peyer's patches but jejunum and duodenum is not having it.
Answer:
The correct option is C. <u>Fever </u> occurs when the innate immune system is attempting to flush a specific area with phagocytes.
Explanation:
Phagocytes can be described as components of the immune system that attack foreign antigens. Fever causes some kinds of immune cells to fight better. A fever is generally caused when an enormous number of phagocytes are transported to an area to fight pathogens. The hypothalamus is part of the brain that determines the regulation of the body temperature. It also plays an active role in generating fevers at inflammation sites.
Answer: During sexual intercouarse a males ejaculation fertilizes the egg and is released. Once the egg travles to the uterus. It will usually implant in endometrium. From there a hormone called human chorionic gonadotropin begins to produce in the uturus. This is the hormone that a pregnancy test measures. It prevents the uterine lining from being shed, so the woman does not have a period. Resulting in pregnancy.
