Through muscle contractions, we are able to run, walk, lift, […]
Variables Effecting Vital Capacities Among Undergraduate Biology Students
Reference this Share this: Facebook Twitter Reddit LinkedIn WhatsApp Abstract Vital capacity’s importance is to determine an individual’s lung function, or how what volume of air can be expelled from a person’s lungs. In this study, we investigated the relationships between vital capacity and heart rate, chest circumference, height, gender, and stature in undergraduate Biology students. This was measured via […]

Vascular Reactivity in Hypertension Introduction High blood pressure (hypertension) is one of the most important preventable causes of morbidity and premature death in the world. The major risk factor for ischemic and myocardial infarction, heart failure, chronic renal failure, premature death, cognitive decline and hemorrhagic stroke is hypertention.

Vocabulary and Key Definitions in the Human Body
The endocrine system works with the nervous system and circulatory system to regulate the body’s activities of cells, tissues, and organs. The nervous system triggers the endocrine system to contract the specific gland and secrete a specific hormone to keep the body in homeostasis. The hormones bind to a protein to hitch a ride using […]
Voltages of Antagonistic Muscles Against the Moment of Exerted Loads
Reference this Share this: Facebook Twitter Reddit LinkedIn WhatsApp Holding a weight at increasing length from the elbow The actions of many muscles are antagonistic in nature, especially in the muscles of the limbs. A small portion of the effort in countering loads is exerted by one muscle, will a bigger portion of the effort exerted to counter a load […]
Wallace Model Policy Ineffectiveness Proposition
Critically discuss the following statement: “The Sargent and Wallace (1976) model of policy ineffectiveness has no basis in reality. It is of no practical or theoretical value to policymakers and economists alike.” The Sargent & Wallace model (1976) produced the ‘Policy Ineffectiveness Proposition” which is viewed as a radical turning point for monetary theory and […]
