Which tissue carries oxygen around the body?

Question: Which tissue carries oxygen around the body?

Answer:

  • Blood is a type of connective tissue that carries oxygen around the body.
  • Within the blood, there are specialized cells called red blood cells (erythrocytes) that are responsible for carrying oxygen.
  • Red blood cells contain a protein called hemoglobin, which binds to oxygen in the lungs and releases it in tissues.
  • As blood circulates through the body, red blood cells pick up oxygen from the lungs during inhalation and deliver it to cells in different organs and tissues.

Function

 

·        Carries oxygen, nutrients, hormones, and waste products to and from cells.

·        Fights against pathogens and foreign substances through white blood cells and antibodies.

·        Helps maintain body temperature, pH balance, and fluid balance

·        Clotting: Forms blood clots to prevent excessive bleeding.

pH ·        The pH of blood is slightly alkaline, ranging from 7.35 to 7.45.
Components ·        Red Blood Cells (Erythrocytes

·        White Blood Cells (Leukocytes)

·        Platelets

·        Plasma

Amount in Body ·        In an average adult, blood volume is approximately 5 liters (about 8% of body weight).
Production ·        Blood cells are formed in the bone marrow through a process called hematopoiesis.

·        Red blood cells, white blood cells, and platelets are continuously produced to replenish the blood supply.

Unique Facts

 

·        Blood is composed of about 55% plasma and 45% cellular components

·        The average lifespan of a red blood cell is around 120 days

·        Blood type is determined by the presence or absence of specific antigens on the red blood cell surface

·        Blood can be donated and transfused to save lives
