Description : Check out this medical PowerPoint presentation titled "Circulatory System - BLOOD, Blood vessels, Heart and lymph vessels”.

This medical PowerPoint presentation is about the circulatory system, a complex network of organs, vessels, and tissues that work together to transport blood, oxygen, and nutrients throughout the body. Its primary function is to supply oxygen and nutrients to the bodys cells and tissues and remove waste products and carbon dioxide from them.

The circulatory system consists of the heart, blood vessels, and blood. The heart is a muscular organ that pumps blood through the blood vessels, which are divided into three types: arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to the bodys tissues, while veins carry oxygen-poor blood back to the heart. Capillaries are tiny, thin-walled vessels that allow for the exchange of oxygen, nutrients, and waste products between the blood and the bodys tissues.

Blood is a fluid that carries oxygen, nutrients, hormones, and other important substances throughout the body. It is composed of plasma, which is a liquid portion that contains water, salts, and proteins, as well as cellular components such as red blood cells, white blood cells, and platelets.

The circulatory system also plays an important role in maintaining homeostasis, which is the bodys ability to maintain a stable internal environment. It helps regulate body temperature, pH levels, and electrolyte balance.

Diseases of the circulatory system can have serious consequences, such as heart attack, stroke, and hypertension (high blood pressure). Therefore, it is important to maintain a healthy lifestyle and receive regular medical check-ups to prevent and detect any potential issues with the circulatory system.

Transcript

Slide 1-

Circulatory SystemBLOODBlood vesselsHeartlymph vessels Provides a rapid transport of nutrients, waste products, respiratory gases and cells Powered by the pumping action of the heart
Slide 2-

Functions Of Blood Transportation - the blood transports dissolved gases, nutrients, hormones and metabolic wastes. Protection - the blood restricts fluid losses through damaged vessels. Platelets in the blood and clotting proteins minimize blood loss when a blood vessel is damaged. Regulation Blood regulates the pH and electrolyte composition of the interstitial fluids. Blood regulates body temperature.
Slide 3-

Composition Of Blood Contains cellular and liquid components A specialized connective tissue Blood cells – formed elements Plasma – fluid portion and fibrinogen Blood volume Males: 5 – 6 liters Females: 4 – 5 liters The pH of blood is about 7.35-7.45
Slide 4-

Formed Elements Blood cells Erythrocytes, leukocytes, and platelets Staining of blood cells Acidic dye – eosin – stains pink Basic dye – methylene blue – stains blue and purple
Slide 5-

Blood Plasma Straw-colored, sticky fluid portion of blood Approximately 90% water Contains: Ions – Na+ and Cl- Nutrients – sugars, amino acids, lipids, cholesterol, vitamins and trace elements Three main proteins - Albumin (60%), globulin (35%), fibrinogen (4%) Dissolved Gasses – including O2 and CO2 Waste Products – other protein wastes such as urea and bilirubin
Slide 6-

Composition of Blood Hematocrit – measure of % RBC Males: 47% ± 5% Females: 42% ± 5% Figure 17.1
Slide 7-

Figure 19.1b Composition of Whole Blood
Slide 8-

Slide 10-

Erythrocytes – Red Blood Cells (RBCs) Oxygen-transporting cells 7.5 µm in diameter (diameter of capillary 8 – 10µm) Most numerous of the formed elements Females: 4.3 – 5.2 million cells/cubic millimeter Males: 5.2 – 5.8 million cells/cubic millimeter Made in the red bone marrow in long bones, cranial bones, ribs, sternum, and vertebrae Average lifespan 100 – 120 days
Slide 11-

RBC Structure And Function Have no organelles or nuclei Hemoglobin – oxygen carrying protein Each RBC has about 280 million hemoglobin molecules Biconcave shape – 30% more surface area
Slide 12-

Leukocytes – White Blood Cells (WBCs) Protect the body from infectious microorganisms 4,800 – 11,000/cubic millimeter Function outside the bloodstream in loose connective tissue Diapedesis – circulating leukocytes leave the capillaries WBCs have a nucleus and are larger than RBCs Most produced in bone marrow Lifespan of 12 hours to several years
Slide 13-

Leukocytes – White Blood Cells (WBCs) Two types of leukocytes Granulocytes Agranulocytes Differential WBC Count Never Let Monkeys Eat Bananas Figure 17.5
Slide 14-

Granulocytes Neutrophils – most numerous WBC Phagocytize and destroy bacteria Nucleus – has two to six lobes Granules pick up acidic and basic stains Figure 17.4a
Slide 15-

Eosinophils – compose 1 – 4% of all WBCs Play roles in ending allergic reactions, parasitic infections Figure 17.4b Granulocytes
Slide 16-

Granulocytes Basophils – about 0.5% of all leukocytes Nucleus – usually two lobes Granules secrete histamines Function in inflammation mediation, similar in function to mast cells
Slide 17-

Agranulocytes Lymphocytes – compose 20 – 45% of WBCs The most important cells of the immune system Nucleus – stains dark purple Effective in fighting infectious organisms Act against a specific foreign molecule (antigen) Two main classes of lymphocyte T cells – attack foreign cells directly B cells – multiply to become plasma cells that secrete antibodies Figure 17.4d
Slide 18-

Agranulocytes Monocytes – compose 4–8% of WBCs The largest leukocytes Nucleus – kidney shaped Transform into macrophages Phagocytic cells Figure 17.4e
