Spleen: Key Functions and Blood Filtration
- The splenic hilum and gastric surface are key parts of the spleen, along with the pancreatic and renal surfaces.
- The splenic artery supplies oxygenated blood to the spleen, while the splenic vein drains blood from it.
- The spleen contains red pulp, which filters blood of antigens, microorganisms, and defective red blood cells.
- White pulp in the spleen is part of the immune system, primarily composed of white blood cells.
- Trabeculae form the framework of the spleen, attached to the capsule, with thin vascular sinusoids draining into bulbanes.
- The spleen filters damaged red blood cells through macrophages in the red pulp, turning them into conjugated bilirubin.
- The white pulp consists entirely of lymphoid tissue, producing white blood cells and antibodies to fight sickness and disease.
- The spleen stores up to a cup of blood for emergencies and platelets to aid in blood clotting.
- The kidneys filter blood through nephrons, with the renal arteries supplying blood and the renal vein returning it to circulation.
- The heart pumps blood through four chambers, with valves controlling blood flow, and it can beat over 100,000 times a day, circulating about 2,000 gallons of blood.

"Human Body Anatomy: Bones and Muscles"
- The human body consists of 206 bones, with the spinal column being a crucial part. It comprises the cervical vertebrae (7 bones in the neck), thoracic vertebrae (12 bones in the mid-back), lumbar vertebrae (lower back), sacrum (connected to the pelvis), and coccyx (fusion of bones at the base).
- Muscles in the human body total around 650, with key ones like the deltoids (3 parts on the shoulders), pectorals (major and minor on the chest), biceps (help in lifting), triceps (on the back of the arm), abdominals (4 muscles on the tummy), gluteus maximus (largest muscle on the rear end), quadriceps (4 muscles on the front thigh), and hamstrings (3 muscles on the back of the thigh).
- Understanding the anatomy of muscles is vital for maintaining strength and mobility, with each muscle group playing a specific role in movement and support throughout the body. Taking care of bones and muscles is essential for overall health and longevity.
