Basic Plant Anatomy: Roots, Stems, and Leaves

61.5K
The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

392
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Overview of the Vascular System01:20

Overview of the Vascular System

3.1K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Blood Studies I: ABG and VBG

809
Blood studies are critical in the medical field, enabling healthcare professionals to assess a patient's health status accurately. This page will focus on two significant blood studies: Arterial Blood Gas (ABG) and Venous Blood Gas (VBG).
Arterial Blood Gas (ABG)
Arterial Blood Gas (ABG) studies are crucial for assessing the lungs' ability to supply oxygen and remove carbon dioxide, reflecting the patient's ventilation status. They also help understand the kidneys' capacity to...

Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

2.8K
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

Autoregulation of Blood Flow01:17

Autoregulation of Blood Flow

3.8K
Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation....

Area of Science:

  • Ethnobotany
  • Dermatology
  • Pharmacology

Background:

  • Bloodroot (Sanguinaria canadensis) is a North American plant with a history of medicinal use.
  • Traditional applications include antimicrobial, antihypertensive, anti-inflammatory, and antineoplastic properties.
  • In dermatology, its cytotoxic effects have led to its use in treatments like black salve.

Purpose of the Study:

  • To raise awareness of the dual nature of Sanguinaria canadensis.
  • To highlight both the therapeutic potential and the significant toxicities associated with its use.
