Presentation on the topic "Blood" in biology in powerpoint format. This presentation for 8th grade schoolchildren gives the definition of blood, briefly describes the composition of blood, and also provides reinforcement material in the form of a crossword puzzle. The work contains 12 slides. Author of the presentation: Hannanova Valentina Nikolaevna.
Fragments from the presentation
Blood - internal environment organism formed by liquid connective tissue. Consists of plasma and formed elements: leukocyte cells and postcellular structures (erythrocytes and platelets). On average, the mass fraction of blood to the total body weight of a person is 6.5-7%
Blood composition
- erythrocyte
- platelet
- leukocyte
Do you know?
The power of the human heart is no more than 0.8 W; The human heart pumps 30 tons of blood per day; the blood turnover period is big circle blood circulation is 21c, and in the low blood circulation - 7c. Think about why this is possible? Why does this logical paradox not contradict the laws of physics?
Blood plasma contains water and substances dissolved in it - proteins albumin, globulins and fibrinogen. About 85% of plasma is water. Inorganic substances make up about 2-3%; these are cations (Na+, K+, Mg2+, Ca2+) and anions (HCO3-, Cl-, PO43-, SO42-). Organic matter(about 9%) proteins, amino acids, urea, creatinine, ammonia, glucose, fatty acid, pyruvate, lactate, phospholipids, triacylglycerols, cholesterol. Blood plasma also contains gases oxygen, carbon dioxide and biologically active substances hormones, vitamins, enzymes, mediators
Red blood cells(red blood cells) are the most numerous of the formed elements. Mature red blood cells do not contain a nucleus and have the shape of biconcave discs. Red blood cells contain iron-containing protein - hemoglobin. It provides the main function of red blood cells - transport of gases, primarily oxygen.
Platelets(blood plates) are limited cell membrane fragments of the cytoplasm of giant cells Together with blood plasma proteins (for example, fibrinogen), they ensure the coagulation of blood flowing from a damaged vessel.
Leukocytes- white blood cells; heterogeneous group of different appearance and functions of human or animal blood cells, identified on the basis of the absence of independent coloring and the presence of a nucleus.
Answer the questions and complete the crossword puzzle
Vertically:
- A formed element of blood that provides gas exchange.
- The liquid part of the blood that does not belong to the formed elements.
- Part of the cell missing from red blood cells and platelets.
Horizontally:
- A formed element responsible for the body's immunity.
- A uniform element that begins to work in case of injuries and wounds.
- It is liquid, but belongs to connective tissue.
- A vital gas that transports red blood cells.

Blood functions
- Transport function.
- Protective function.
- Humoral regulation of the body is carried out.
- Erythrocytes are red blood cells.
Duration
The life of an erythrocyte is about four months.
Therefore human blood
constantly updated with new ones
red blood cells.
- When blood vessels are injured, blood clots
melts, forming a clot - a thrombus,
preventing the flow of blood.
The basis of the thrombus is fibrous
fibrin, a fibrin protein formed
from protein dissolved in plasma –
fibrinogen.
LEUKOCYTES.
- Leukocytes are
colorless blood cells. They all have kernels.
In 1 cu. mm of blood contains 6-8 thousand. leukocytes.
Immunity.
- Immunity is one defense mechanism. The immune system protects the body
from infectious diseases.
TYPES OF IMMUNITY:
- INNATE IMMUNITY.
- ACQUIRED IMMUNITY.
- NATURAL IMMUNITY.
- ARTIFICIAL IMMUNITY.
