The integumentary system comprises the skin and its appendages acting to protect the body from various kinds of damage, such as loss of water or damages from outside. The integumentary system includes hair, scales, feathers, hooves, and nails. It has a variety of additional functions; it may serv...

Respiratory system: nose pharynx larynx trachea bronchi lungs Respiratory system’s primary function: Furnish oxygen (O2) for use by individual tissue cells and take away their gaseous waste product, carbon dioxide (CO2), through act of respiration. External respiration Lungs are vent...
Chemical Buffers - protein buffer, phosphate buffer system and bicarbonate buffer system
By: HWC, Views: 7951
• There are a variety of chemicals in body fluids that prevent the fluids from undergoing large changes in. • These chemicals buffer or regulate fluctuations in H+ concentration. • Chemical buffers: • Bind to H+ ions when there are too many in a solution so pH remains normal. •...

• The PNS consists of all nervous tissue outside of the CNS. • It is divided into three functional components: • Somatic nervous system (SNS) • Autonomic nervous system (ANS) • Enteric nervous system (ENS) • The SNS consists of: • Sensory neurons from skeletal muscles ...
Role of the respiratory system - effect of altered ventilation rates

• The blood flow redistributes fluids that have different pH values between body regions. • The regulation of the blood pH is important to maintain homeostasis. • Blood pH is regulated by: • Chemical buffers. • The respiratory system. • The urinary system. • All thes...
Coaductile pathway, Timing of contraction signal & Conduction system and ECG
By: HWC, Views: 7926
• When the system is healthy, the signal to contract the entire conduction system originates in the SA node - known as the heart's pacemaker. • The SA node triggers contraction because it depolarizes at a faster rate than other parts of the conduction system. • The wave of excitation fr...
Hormonal regulation of blood pressure - RAA system
By: HWC, Views: 8158
■ Long-term regulation of MABP is under hormonal control. • Hormones that affect blood pressure and volume: the renin-angiotensin-aldosterone (RAA) system, antidiuretic hormone (ADM), and atrial natriuretic peptide (ANP). ■ Most important hormonal regulator of MABP. Activated by drop in...
