In step form, explain how.......
Food is processed in the digestive system
Air is processed in the respiratory system
Blood flows through your heart
After that please answer the following questions:
How many bones are in the human body?
In 10 sentences explain what the cerebellum, medulla, cerebrum, hypothalamus. and spinal cord does for our Central Nervous system.
Answer:
1) As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
2) Process on how air passes through the respiratory system
Breathing in
They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air travels to the alveoli, or air sacs.
3) How does blood flow through the heart? Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
4) The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.
5) Cerebrum is associated with higher brain function such as thought and action.
Cerebellum is associated with regulation and coordination of movement, posture, and balance.
Medulla Oblongata controls involuntary actions like breathing, heart function, blood vessel function, digestion, sneezing, and swallowing.
