Body Systems

- Kidneys: Collect waste from blood- Bladder: Stores urine until removal- Urethra: Urine exits throught urethra- Ureters: Carry urine from the kidneys to the bladder

1. Intercalated cells: maintain the acid base balance (blood pH)2. Principal cells: maintain water sodium balance. Secretes K+ and reabsorbs NA.

Removes liquid wastes in the body in the form of urine, keeps a stable balance of salts in the body and produces a hormone called erythropoietin which helps form red blood cells.

Cardiovascular diseaseCause: Blood flow to the heart, brain or body can be reduced as the result of a blood clot or by arteries to harden. Symptoms: Chest pain, discomfort,shortness of , pain

- Heart: A pump that moves the blood through the body- Blood vessels: They transport the blood. The most important blood vessels are the arteries and veins which carry blood away or towards the heart.

Transport of nutriets, oxygen, and hormones to cells throughout the body and removal of co2 and nitrogenous wastes.

Cardiovascular System

Cell structure and function

Principle cells and intercalated cells: collecting ducts, consists of ducts that connect the nephrons to the ureter. It works in electrolyte and fluid balance through reabsorption.

Urinary Tract Infection

The urinary system maintains homeostasis by removing wastes from the body, regulating blood activity, regulating electrolyte balance, regulating acid-base homeostasis and regulating blood pressure, volume, and pH.

Causes: Since the urethra is close to the anus, bacteria from the anus invade the urethra. Symptoms: strong urge to urinate, small amount of urine and burning sensation while urinating.

1. Red blood cells: Transport oxygen and co2 to and from the tissues.2. White blood cells: Helps the body fight diseases and infections

Types of cells

Sweating: Our cappiaries allow heat from the blood to radiate of the skin which lowers body temp. This prevents overheating. Heart rate: When we exercise, we consume more oxygen than usual so, our heart rate speeds up. That way, the heart pumps blood faster which helps maintaiin homeostasis.

How it maintains homeostasis

Red blood cells: Haemoglobin combines with oxygen and transports to the cells. Then, it returns co2 waste to lungs. White blood cells: When a tissue is damaged, white blood cells increase to fight the bacteria or infection.
