Endocrine Hormones: Endocrine hormones are chemical messengers secreted by endocrine glands, regulating processes like metabolism, growth, and reproduction. Examples include insulin, adrenaline, and thyroid hormones.
Endocrine Glands Secrete: Endocrine glands secrete hormones directly into the bloodstream. These hormones regulate metabolism, growth, reproduction, and stress responses.
Endocrine Glands And Their Functions: Endocrine glands release hormones to regulate growth, metabolism, and reproduction; key glands include the thyroid, pituitary, and adrenal glands.
Endocrine And Exocrine Glands: Endocrine glands secrete hormones into the bloodstream (like the thyroid), while exocrine glands release substances through ducts (like sweat or salivary glands).
Endocrine Anatomy: Endocrine anatomy covers hormone-secreting glands such as the pituitary, thyroid, adrenal, and pancreas, all critical in regulating body processes like growth and metabolism.
Diagram Of Veins: A diagram of veins shows the blood vessels responsible for returning deoxygenated blood to the heart, including the superior and inferior vena cava and other major veins.
Diagram Of Urinary System: A urinary system diagram typically shows the kidneys, ureters, bladder, and urethra. It explains how urine is produced, stored, and excreted, playing a vital role in waste removal and fluid balance.
Diagram Of The Urinary System: A diagram of the urinary system shows the kidneys, ureters, bladder, and urethra. It helps to visualize how the body filters blood and removes waste through urine.
Diagram Of Endocrine System: This diagram shows glands such as the pituitary, thyroid, adrenal, and pancreas, which produce hormones that regulate body processes like metabolism and growth.
Common Femoral Artery: The common femoral artery is a major blood vessel in the thigh that supplies blood to the lower extremities.
Circumflex Artery: The circumflex artery is a branch of the left coronary artery. It supplies blood to the left atrium, left ventricle, and parts of the interventricular septum, crucial for heart function.
Celiac Artery Function: The celiac artery supplies oxygenated blood to organs in the upper abdomen, including the stomach, liver, spleen, and pancreas.
Carotid Artery Location: The carotid arteries are located on either side of the neck, and they supply oxygenated blood to the brain, neck, and face. These arteries are essential for brain function and are often palpated to check pulse rate.
Cardiac Tissue Function: Cardiac tissue, found only in the heart, contracts rhythmically and involuntarily to pump blood throughout the body, powered by electrical impulses.
Cardiac Muscle Fibers: Cardiac muscle fibers are striated, branched cells found only in the heart; they contract rhythmically and are connected by intercalated discs for synchronized heartbeats.
Cardiac Muscle Cell: A cardiac muscle cell, or cardiomyocyte, is a specialized muscle fiber found only in the heart, characterized by striations and intercalated discs that facilitate synchronized contractions.
Cardiac Cells: Cardiac cells, or cardiomyocytes, are specialized muscle cells that make up the heart and are responsible for heart contraction.
Cardiac And Pyloric Sphincter: The cardiac sphincter is a muscle located between the esophagus and stomach, preventing acid reflux. The pyloric sphincter controls the flow of partially digested food from the stomach into the small intestine, regulating digestion.
Artery In Neck: The main artery in the neck is the carotid artery, which supplies oxygen-rich blood to the brain, face, and neck.
Artery And Vein: Arteries carry oxygenated blood away from the heart, while veins return deoxygenated blood to the heart, working together to maintain circulation throughout the body.
