How does haemoglobin supply the tissues of the body with oxygen?
Hemoglobin carries oxygen in red blood cells from the lungs to the tissues of the body. In the lungs, oxygen binds to the iron in hemoglobin to form oxyhemoglobin, which is then transported via the bloodstream to tissues where oxygen is released for cellular respiration. This process is facilitated by the concentration gradient of oxygen between the lungs and tissues.
What supply of oxygen exists in the body at any one time?
The body carries about 1-1.5 liters of oxygen in the blood and tissues at any given time. This supply is continually replenished through breathing and circulation to meet the body's oxygen demands.
What term describes the condition of having subnormal levels of oxygen in the cells?
Hypoxia is the condition characterized by subnormal levels of oxygen in the body's tissues and cells. This can lead to various health issues due to the insufficient oxygen supply.
What side of the heart is rich in oxygen?
The left side of the heart is rich in oxygen because it receives blood from the lungs, where it picks up oxygen through gas exchange. This oxygen-rich blood is then pumped out to the rest of the body to supply tissues with the oxygen they need for cellular function.
What supply of oxygen exist in the body at any time?
The body's oxygen supply primarily comes from breathing air into the lungs, where oxygen is absorbed by red blood cells and then transported throughout the body. Additionally, oxygen is stored in the body in the form of oxyhemoglobin in the blood and myoglobin in muscle tissue. The body can also store a reserve of oxygen in the form of dissolved oxygen in the blood and tissues.
How do tissues get the oxygen they need for energy production?
The tissues get oxygen from oxygenated blood supply for energy production.
What is a state of disruption of oxygen supply to the tissues and a return of blood to the heart?
anoxia

What does the vascular system do?
Pumps blood around the body, to supply the tissues with oxygen and nutrients and to transport waste products away from these tissues.
What do vascular systems do?
Pumps blood around the body, to supply the tissues with oxygen and nutrients and to transport waste products away from these tissues.
What lack of protein will decrease oxygen supply to body tissues?
A lack of protein in the diet can lead to decreased production of hemoglobin, which carries oxygen in red blood cells. This can result in decreased oxygen supply to body tissues and lead to symptoms like fatigue, weakness, and shortness of breath.
What are the red blood cells used for?
RBC used to supply oxygen and get back co2from tissues.
Why do avascular tissues heal slowly?
Avascular tissues have limited access to blood supply, which is important for delivering oxygen and nutrients necessary for healing. Without sufficient blood flow, the healing process is slowed down in avascular tissues.
What is the medical term meaning tissues without their own blood supply?
The medical term for tissues without their own blood supply is avascular tissue. These tissues rely on diffusion to obtain nutrients and oxygen from nearby blood vessels. Examples include cartilage and cornea.
What does the human respiratory system?
The respiratory system purifies and oxygenates the blood, so that there is constant supply of oxygen to the tissues.
What is the difference between hypoxia and ischemia?
simply, Hypoxia is less oxygen supply to cell tissues, while the Ischemia is less blood supply to cell issues.
What supply of oxygen exists in the body at any one time?
The body carries about 1-1.5 liters of oxygen in the blood and tissues at any given time. This supply is continually replenished through breathing and circulation to meet the body's oxygen demands.
