The digestive works to break down food eaten before exercising.
The digestive system is responsible for the process of digestion, which involves the breaking down of the consumed food into smaller parts which can be absorbed by the body. This system is comprised of the gastrointestinal tract and several organs participating in digestion, which are the tongue, salivary glands, pancreas, liver, and gallbladder.
The circulatory takes in the nutrients obtained from the food.
The circulatory system (also known as cardiovascular system) is responsible for circulating blood through the body and transporting nutrients and many other chemicals. The heart and the lungs are two critical components of this system since blood flows through the lungs and oxygenates. This oxygenated blood is pumped through the heart to the rest of the body.
The body sweats as a mechanism to cool off, because the excretory is working to flush out toxins.
The excretory system is responsible for removing excess and unnecessary materials from the body fluids of an organism. The main organ system involved in this system is urinary system, however, excretion is also achieved through breathing and sweating.

i did the test
Explanation:
Answer:
b. Red blood cells that lack nuclei
d. A fully erect posture associated with bipedalism

Eccrine glands can be found on horses, you may have seen horses sweeting. The pressure sensors can be found in other apes too. Fully erect posture is a characteristic of humans, other apes or monkeys may walk sometime like this, but their main locomotion is in 4 extremities. Non nucleated is a characteristic that gives an advantage because more oxygen can be carried inside red blood cells making respiration more efficient.
Answer:
chemotaxis of phagocytes
Explanation:
Histamine is a chemical involved in inflammation but it also has role as a neurotransmmiter in central nervous system and uterus It is synthesized by the two types of cells: basophils and mast cells and it acts via binding to its receptors (histamine receptors). Roles of histamine are:
- vasodilatation and consequently decrease in the blood pressure
- increase vascular permability in the nose cavity (runny nose)
- regulates sleep-wake cycle
- stimulates gastric acid secretion in the stomach etc.
