Urinary System: Anatomy, Function, and Pathology
Anatomy of the Urinary System
The urinary system is composed of two kidneys, two ureters, the bladder, and the urethra.
Composition of the Nephron
The kidney is made up of multiple nephrons. The nephron is the structural and functional unit of the kidney. It is composed of:
- Glomerulus: A network of capillaries that receive blood from an afferent arteriole and drain through an efferent arteriole.
- Bowman’s capsule: Surrounds the glomerulus and has an open portion for collecting urine filtered in the glomerulus.
Cellular Respiration and Fermentation: Energy Production
The process involves the complete oxidation of acetyl-CoA, which is excreted as carbon dioxide. e-/ H + obtained in the successive oxidations are used to form molecules of reducing power and chemical energy in the form of GTP. This formation energy is known as substrate-level phosphorylation. In summary, the Krebs cycle occurs as follows: acetyl-CoA joins oxaloacetic acid to form citric acid, liberating CoA. Then, a series of reactions produce oxaloacetic acid again. This sequence includes the

Nuclear Learning as an Element of Education
Definitions of education lie in the essential idea of driving the development of a person in a perfective sense, plenificación, or tending to personal excellence. The different learning are interconnected to form an integrated, unique, and global whole. The person is, therefore, an indivisible whole in a state of development that corresponds to a set of learning organized as a single system and, as such, interacts with the environment.
The consideration

Introduction to Nutrition and Human Body Systems
Nutrition is the life function that enables living beings to obtain matter and energy. The systems involved are:
- Digestive System: This system transforms the food we eat into nutrients, which are absorbed and passed into the bloodstream.
- Respiratory System: This system takes oxygen from the air and transfers it to the blood. It also takes carbon dioxide from the blood and expels it out of the body.
- Circulatory System: This system uses blood to carry nutrients
The Internal Environment and Circulatory System
The Internal Environment and the Circulatory System
The internal environment is the fluid surrounding the cells of an organism. Cells extract nutrients and oxygen, and necessary substances are discharged as waste and carbon dioxide. It is made up of:
- Interstitial plasma: A liquid between the cells that functions in nutrition and defense. It originates from blood that has been filtered through the thin walls of blood capillaries.
- Blood and lymph: Lymph is a liquid formed from interstitial plasma that
Microorganisms: Pharmaceutical and Immunological Uses
Microorganisms in the Pharmaceutical Industry
Microorganisms play a crucial role in the pharmaceutical industry. Antibiotics, for instance, are antimicrobial chemical compounds synthesized by fungi and bacteria.
Fleming’s accidental discovery of penicillin, by contaminating a Petri dish, highlighted this. He noted that the fungus secreted a substance that destroyed bacterial colonies. Penicillin is particularly effective against Gram-positive bacteria. Later, streptomycin was discovered, proving effective
