Answer 1

Answer:

The answer is as follows:-

Explanation:

(1).It is composed of (1) spinal nerves, (2) cranial nerves, and (3) certain parts of the autonomic nervous system.

(2).The pericardium is the name given to the membranes which cover the heart.

(3).The Kidneys Are Composed of Three Main Sections. Each kidney consists of an outer renal cortex, an inner renal medulla, and a renal pelvis. Blood is filtered in the renal cortex.

(4).The testes are situated outside the abdominal cavity within a pouch called scrotum. The scrotum helps in maintaining the low temperature of the testes (2–2. 5o C lower than the normal internal body temperature), which is necessary for spermatogenesis.

(5).The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. ... As a result, the lungs contract and air is forced out

(6).The wide gap that seperates the incisors (or dental pad on the maxilla) from the premolars is called the diastema.
