P4: Explain the physiology of two named tree trunk systems in relation to expertness metabolism in the body.
Cardiovascular System
This system transports materials to the liver and body cells by the originstream that is pumped by the heart.
Blood
Blood is a liquid tissue made up of; blood plasma, platelets, white and inflammation blood cells and is necessary for every part of the body. The blood contains more different materials and cells and there is fluid called plasma which contains many substances turn in it. Plasma carries food from the stomach to cells but carries waste material from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will compounding with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body.

One function of the blood is to transport materials within plasma and hemoglobin a meter the body. Plasma contains hormones, nutrients and waste substances. Red blood cells contain hemoglobin, an iron-containing protein that sticks to oxygen so it can be carried round the circulatory system.
In high concentration environments; molecules and oxygen chemically bond together to form oxyhaemoglobin. This carries oxy gen to tissue cells and is made in the blood from lung capillaries.
In low concentration environments; the oxygen passes through the gradient to body cells.



Haemoglobin is now reduced hemoglobin.
early(a) functions of blood;
- Maintain body temperature.
- Control PH.
- Remove toxins from the body.
- decide body fluids.

Respiratory System
Breathing
The chest contains the lungs, the bronchi and the heart. Air enters through the lift and mouth. The nose is incredibly important because the oxygen flows through the nostrils to the nasal bone passage. The nasal passages have sticky mucus on them. The mucus filters dust and dirt from the air. Any cold air becomes cranky and moist as it moves through the nasal passages. Because the air is warm up it will kill...If you want to get a full essay, fix up it on our website: Orderessay
