Cardiovascular system
The heart weighs between 250-350 g in men and between 200-300 g in women, in addition the heart is white, but it is reddish for blood, it also has blue and red colors for veins and arteries.
Description
Protects the body from infections and diseases; It fights everything from cold and flu viruses to serious illnesses like cancer. Our immune systems are complex and are influenced by many factors.
Description
The heart develops from a tube-like structure called the primitive heart tube in the embryo. Through folding, looping, and septation processes, the heart is transformed into a four-chambered structure. The fold brings the ends of the tube together, while the loop creates a curved shape. Septation involves the growth and fusion of tissues, forming partitions that divide the heart into chambers. The atrial septum separates the atria, while the ventricular septum divides the ventricles. These complex processes give rise to specialized structures of the heart, such as valves and muscular walls, which allow efficient pumping of blood throughout the body. Interruptions during development can lead to congenital heart defects, which may require medical intervention.
Chronological Order
Autoimmune diseases occur when the immune system mistakenly targets and attacks healthy cells and tissues in the body. Examples include rheumatoid arthritis, lupus, and multiple sclerosis. Treatment of autoimmune diseases generally involves drugs that suppress or modulate the immune response, such as corticosteroids, immunosuppressants, or biologic therapies.
Problem-solution
Blood enters the atrium from the right side of the body, moves into the right ventricle, and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins, into the left atrium, into the left ventricle, and out to the body tissues through the aorta.
Sequence
When pathogens such as bacteria, viruses, or other foreign substances enter the body, specialized immune cells recognize them as antigens. Antigens are molecules that trigger an immune response.
Cause-Effect
Arteriosclerosis is when the arteries through which the blood flows become clogged due to fat, which can be a problem since the blood does not arrive properly, but this can be fixed with changes in diet or surgical procedures
Problem-Solution
The nervous system and the immune system are involved in integrated defense responses and contribute to homeostasis with immediate responses to acute stress (physical, psychological or immunological) and maintenance responses.
Compare
Obesity is something that should not be taken lightly, because being overweight can have consequences such as increased stress on the heart, higher blood pressure, increased risk of heart disease, type 2 diabetes, and other cardiovascular conditions.
Cause-effect
The immune system is responsible for defending the body from diseases in the following way: 1-Recognition of the pathogen, 2-Activation of the immune system, 3-Innate immune response, 4-Adaptive immune response, 5-Elimination of the pathogen, 6-Regulation and resolution, 7-Acquired immunity.
