About This Presentation

Description : Check out this medical PowerPoint presentation titled "Blood”.

This medical PowerPoint presentation is about blood, a bodily fluid that circulates through the veins and arteries, providing the body with oxygen, nutrients, and hormones, while removing waste products and carbon dioxide. It is made up of various components, including red blood cells, white blood cells, platelets, and plasma.

Red blood cells contain hemoglobin, a protein that binds to oxygen and transports it throughout the body. White blood cells help fight infections and diseases, while platelets aid in blood clotting to prevent excessive bleeding. Plasma is a yellowish liquid that makes up the majority of blood volume and contains various proteins, electrolytes, and other substances.

Blood is vital for the proper functioning of the bodys organs and systems. It is constantly replenished by the bone marrow, where new blood cells are produced. Blood can also be donated and transfused to individuals who need it due to injury, surgery, or medical conditions that result in blood loss or low blood cell count.

Slide 1-

Blood
Slide 2-

Blood-the “River of Life” Blood is the only fluid tissue in the human body. Blood is classified as a connective tissue. Blood carries nutrients, waste, and body heat through blood vessels. Components of blood Living cells Formed elements Non-living matrix Plasma
Slide 3-

Blood Composition If blood is centrifuged Erythrocytes sink to the bottom (45% of blood, a percentage known as the hematocrit) Buffy coat contains leukocytes and platelets (less than 1% of blood) Buffy coat is a thin, whitish layer between the erythrocytes and plasma Plasma rises to the top (55% of blood) The formed elements (blood cells) make blood heavier and 5 times thicker (more viscous) than water.

Physical Characteristics of Blood Color range Oxygen-rich blood is scarlet red Oxygen-poor blood is dull red pH must remain between 7.35–7.45 Acidosis (pH7. 2) Death (pH 7)
Slide 6-

Physical Characteristics of Blood Blood temperature is slightly higher than body temperature at 100.4°F In a healthy man, blood volume is about 5–6 liters or about 6 quarts Blood makes up 8% of body weight
Slide 7-

Functions of Blood Functions include (More details on next 3 slides) Distributing substances Regulating blood levels of substances Protection
Slide 8-

Distribution Functions Delivering O2 and nutrients to body cells Transporting metabolic wastes to lungs and kidneys for elimination Transporting hormones from endocrine organs to target organs
Slide 9-

Regulation Functions Maintaining body temperature by absorbing and distributing heat Maintaining normal pH using buffers; alkaline reserve of bicarbonate ions Maintaining adequate fluid volume in circulatory system
Slide 10-

Protection Functions Preventing blood loss Plasma proteins and platelets initiate clot formation Preventing infection Antibodies Complement proteins WBCs
Slide 11-

Blood Plasma Composition Composed of approximately 90% water Includes many dissolved substances Nutrients Salts (electrolytes) Respiratory gases Hormones Plasma proteins Waste products
Slide 12-

Blood Plasma Plasma proteins Most abundant solutes in plasma Most plasma proteins are made by liver Various plasma proteins include Albumin—regulates osmotic pressure Fibrinogen: Clotting proteins—help to stem blood loss when a blood vessel is injured Globulins: Antibodies—help protect the body from pathogens
Slide 13-

Blood Plasma: Homeostatic imbalances Acidosis Blood becomes too acidic Alkalosis Blood becomes too basic In each scenario, the respiratory system and kidneys help restore blood pH to normal
Slide 14-

Formed Elements Erythrocytes Red blood cells (RBCs) Leukocytes White blood cells (WBCs) Platelets Cell fragments
